RELATED APPLICATION

This application claims the benefit of U.S. patent application Ser. No. 10/434,444, filed May 7, 2003, and entitled “FENUGREEK SEED BIO-ACTIVE COMPOSITIONS AND METHODS FOR EXTRACTING SAME,” which is incorporated herein by reference.

BACKGROUND

1. Field of the Invention

This invention relates to methods and compositions affecting metabolism, and more particularly, to novel compositions of bio-active components that support metabolism and the transportation of glucose and carbohydrates in animals and humans which are derived from fenugreek seeds and methods for extracting the same.

2. The Background Art

Fenugreek is one of the oldest medicinal herbs and is native to southeastern Europe, northern Africa, and western Asia, but is widely cultivated in other parts of the world. Fenugreek is known technically as Trigonella foenum-graecum, a member of the family Fabaceae, and commonly referred to as Greek hay. As appreciated by those skilled in the art, fenugreek is a legume and typically grows between two to three feet tall with light green leaves and small white flowers. A fenugreek seed pod may contain between ten to twenty small, flat, yellow-brown seeds. Typically, a plant seed is formed having a thick or hard outer coat called a testa and often referred to as a seed coat. The inner portion of the seed coat contains a plant embryo and a nutritive tissue called endosperm, which surrounds the embryo. As the fenugreek seed embryo matures, it consumes endosperm. Fenugreek seeds often have a pungent aroma and may have a bitter taste, which is said to be similar to celery.

Fenugreek has long been used as a medicinal herb and culinary additive in both Asia and the Mediterranean. It is believed that the seed of the fenugreek plant contains many active compounds with pharmaceutical applications such as, for example, iron, vitamin A, vitamin B, vitamin C, phosphates, flavonoids, saponins, trigonelline and other alkaloids. Fenugreek has been taken as a stomach tonic and as a treatment for abdominal ailments. Western scientific research has provided insight into the chemical analysis of fenugreek seeds, together with the extraction of 4-hydroxyisoleucine from Fenugreek seeds, and has suggested some clinical utilities of fenugreek.

Sir L. Fowden conducted research into the analysis of fenugreek. He taught the isolation and purification of 4-hydroxyisoleucine from fenugreek and claimed that it is the principal unbound amino acid contained in the fenugreek seed. (See, Fowden et al, Phytochemistry, 12:1707, (1973).) Further investigation of the prior art suggests that the amino acids of fenugreek seeds may have nutritional value. (See, Sauvaire et al, Nutr Rep Int, 14:527 (1976).) Spectrophotometry methods have also been taught by those skilled in the art in the analysis of steroid sapogenin content of fenugreek seeds and such prior art methods may be generally used in an effort to determine the composition of subfractions of defatted fenugreek. (See, Baccou et al, Analyst, 102:458 (1977); Ribes et al, Proc Soc Exp Biol Med, 182:159 (1986).) In addition, those skilled in the art have used chloroform to extract the amino acid 4-hydroxyisoleucine from fenugreek seeds. (See, Alcock et al, Phytochemistry, 28(7):1835 (1989).) It has been found, however, that chloroform is toxic and generally unacceptable as an extraction method under standards established by the food and drug industry.

Other compounds have also been isolated from fenugreek seeds. In addition to the major isomers (2S,3R,4S)-4-hydroxyisoleucine, minor isomers 4-hydroxyisoleucine and amino acids (Lysine, Histidine and Arginine) have been isolated. Later studies have confirmed the presence of 4-hydroxyisoleucine in fenugreek seeds in two diastereoisomers: the major one being the (2S,3R,4S) configuration, representing about 90% of the total content of 4-hydroxyisoleucine, and the minor one being the (2R,3R,4S) configuration. (See, Alcock, Phytochemistry, 28:1835 (1989).)

As appreciated by those skilled in the art, the major isomer (2S,3R,4S) is presently interesting with respect to experimental evidence indicating its ability to stimulate glucose-induced insulin secretion in micromolar concentrations through a direct effect on pancreatic beta cell stimulation in a glucose dependent manner. Moreover, 4-hydroxyisoleucine is able to interact and induce additive insulinotropic effects (i.e., stimulating or affecting the production and activity of insulin, only in the presence of supranormal glucose concentrations). (See, Sauvaire et al, Diabetes, 47:206 (1998).) Investigation of the prior art also discloses clinical studies to investigate the use of subfractions of fenugreek in conditions of hyperglycemia, glucosuria and hyperlipidemia which have been performed on rats, dogs and human pancreatic tissue. (See, Shani et al, Arch Intern Pharmacodyn Ther, 210:27 (1974); Ribes et al, Ann Nutr Metab, 28: 37 (1984); Valette et al, Athersclerosis, 50:105 (1984); Madar, Nutr Rep Int, 29:1267 (1984).) As appreciated by those skilled in the art, clinical studies conducted on fenugreek have focused on investigating a specific subfraction of the fenugreek seed (e.g., testa and endosperm) or, in the alternative, have focused on the specific effect of 4-hydroxyisoleucine in animals and humans with diabetes or a cholesterol disorder.

Studies have also shown that the natural analogue of 4-hydroxyisoleucine is more effective as an antidiabetic agent than a synthetic version. There is, therefore, a suggestion that the therapeutic effects of 4-hydroxyisoleucine are best obtained from extracts of the fenugreek seed. However, using fenugreek seeds as a raw material source for a nutritional supplement presents some difficulties. For example, one such difficulty or disadvantage stems from the fact that a large dose of fenugreek seeds is usually needed in order to obtain therapeutic and other nutritional effects. Patients or consumers are often unwilling to incorporate even de-fatted and de-bitterized seeds into their diet. Mild gastro-intestinal upset may occur at higher doses with non-defatted seeds. Due to the high fiber content of fenugreek seeds, prolonged and high dosage amounts may result in adverse side effects such as flatus or diarrhea.

The binding capabilities of the fiber in fenugreek seeds may also affect nutrient availability, particularly of minerals. As appreciated, external application of fenugreek seed may result in undesirable skin reactions. Thus, it would be an advancement in the art to provide a method for obtaining bio-active and therapeutic compounds from fenugreek seeds, such that undesirable side effects resulting from ingesting the seed or portions thereof can be avoided.

During the aforementioned research investigations, those skilled in the art developed crude methods for extracting 4-hydroxyisoleucine from fenugreek seeds. These prior art methods and extraction techniques have primarily focused on obtaining a “high-purity” extract of 4-hydroxyisoleucine. For example, the extraction of 4-hydroxyisoleucine using adsorption chromatography is known in the art. Such prior art methods, however, tend to yield only small quantities of 4-hydroxyisoleucine and are typically only suitable for small scale laboratory use. As previously described, an alternative extraction method exercised by those skilled in the art uses a toxic organic solvent, such as chloroform, to extract 4-hydroxyisoleucine from fenugreek seeds, whereby contemplating inherent disadvantages to the consumer. Therefore, and as readily appreciated by those skilled in the art, a safer and more commercially practicable method for extraction of 4-hydroxyisoleucine and other bio-active components from fenugreek seeds is therefore needed.

DESCRIPTIONS OF THE PREFERRED EMBODIMENTS

It will be readily understood that the components of the present invention, as generally described and illustrated in the Figures herein, could be arranged and designed in a wide variety of different configurations. Those of ordinary skill in the art will, of course, appreciate that various modifications to the details herein may be made without departing from the essential characteristics of the invention, as described. Thus, the following more detailed description of the embodiments of the compositions and methods of the present invention, as represented in FIGS. 1 through 19, is not intended to limit the scope of the invention, as claimed, but it is merely representative of the presently preferred embodiments of the invention.

The presently preferred embodiments of the invention will be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout.

The term “diabetes,” when used alone, most commonly refers to diabetes mellitus. Diabetes mellitus is commonly referred to as a disorder of carbohydrate metabolism wherein sugars cannot be properly broken down and utilized by the body. The dysfunction in carbohydrate metabolism may generally be associated with a lack of adequate production of insulin. As appreciated by those skilled in the art, insulin is produced by specialized pancreatic cells known as beta cells of islets of Langerhans. Insulin is secreted by the pancreas and moves throughout the body to regulate sugar metabolism and, more particularly, to regulate glucose levels in the bloodstream. Specifically, insulin interacts with several types of cell surface receptors. One such family of receptors is called glucose transport (GT) receptors. At least seven subtypes of the GT receptor family, designated as 1-7 (GT-1-7), have been identified by those skilled in the art.

Many non-diabetic individuals may experience nutritional and metabolic deficiencies during their lifetime which may significantly impact the proper metabolism of glucose and carbohydrates. For example, some individuals may develop a resistance to insulin. These individuals generally have difficulty metabolizing sugars, but not to the level of an individual with diabetes mellitus. One such condition, generally known as “Syndrome X,” may be characterized by elevated blood glucose levels and fat deposition, especially in the abdominal area. A condition of elevated blood glucose level is sometimes referred to as hyperglycemic or hyperglycemia. In many non-diabetic individuals experiencing nutritional and metabolic deficiencies, it may be advantageous to facilitate and support the proper metabolism of glucose and other carbohydrates in the body. The facilitation and support of glucose and carbohydrate metabolism may be accomplished with the administration of compositions that work synergistically with existing insulin in the regulation of glucose and other carbohydrate metabolism or, in the alternative, through the administration of compositions that have an effect independent of insulin in the regulation of glucose and other carbohydrate metabolism.

Clinical studies conducted by the inventors of the present invention indicate that novel compositions of bio-active compounds extracted from fenugreek seeds, which contain 4-hydroxyisoleucine and one or more amino acids at certain concentrations, effectively enhance the transport of glucose into skeletal muscle cells in response to the presence of glucose transport factor 4 (GT-4) on skeletal muscle cells. It has been well established that the behavior of cells relative to GT-4 is very strongly correlated to the behavior of a cell relative to insulin. Therefore, a supportable indication that compositions of bio-active compounds extracted from fenugreek seeds may be used to enhance glucose transport into skeletal muscles of humans is a primary focus of the present invention.

In addition, novel compositions of bio-active compounds extracted from fenugreek seeds, which contain 4-hydroxyisoleucine and an array of other amino acids may be combined with glucose or other carbohydrates to alter the physiological responses associated with a bolus administration of glucose or other carbohydrates, or produce unique physiological responses. Physiological responses may include an increase in gut absorption of glucose, stimulation of pancreatic beta cells and enhanced disposal of glucose or other carbohydrates.

Thus, the novel compositions and methods of the present invention support the premise that extracts of bio-active compounds from fenugreek seeds tend to enhance a body's response to insulin and, consequently, that the enhancement of glucose transport to skeletal muscles may be effective in reducing glucose deposited in the liver and adipose tissue, thereby reducing fat deposition.

One presently preferred embodiment of a method for diagnosing and addressing weight management of the present invention, designated generally as 5, is best illustrated in FIG. 1. As shown, a method for weight management contemplating the use of a composition of bio-active compounds derived from fenugreek seeds may comprise the steps of: (1) performing weight management analysis 6 of an individual experiencing nutritional and metabolic deficiencies which impact proper metabolism of glucose and carbohydrates; (2) performing fenugreek seed extraction 10 by means of extracting a composition of bio-active compounds from fenugreek seeds; and (3) enhancing skeletal muscle glucose transportation 8 within the body of the targeted individual by delivery of a composition of fenugreek seed extract.

The step of performing weight management 6 includes diagnosing a condition of ineffective insulin production, insensitivity to insulin or insulin resistance of the targeted individual. Diagnosing may also include recognizing a condition of obesity or the like. In addition, the step of performing weight management 6, as contemplated herein, may further include the periodic administration of one or more compositions of bio-active compounds derived from fenugreek seeds and a suggested modification of the targeted individual's exercise habits and diet.

The step of performing fenugreek seed extraction 10 comprises the step of extracting a composition of bio-active compounds derived from fenugreek seeds, wherein the composition comprises 4-hydroxyisoleucine and an array of other amino acids based on an established ratio. Further, the step of performing fenugreek seed extraction 10 may also include the step of packaging or conditioning of the fenugreek seed extract for consumption by the targeted consumer. For example, the composition extract of bio-active compounds derived from fenugreek seeds may be packaged and presented as a solid (i.e., a pill, powder, tablet or capsule) or dispensed in the form of a liquid, suspension or the like. Providing the novel compositions of fenugreek seed extract may also involve modifying or conditioning the composition extract such that the extract, when introduced into the consumer's body, will reach the targeted tissue in an effective manner. In one presently preferred embodiment of the present invention, a method of fenugreek seed extraction, generally designed as 10, in best illustrated in FIG. 2 and discussed in further detail hereinbelow.

Still referring to FIG. 1, the step of enhancing skeletal muscle glucose transportation 8 within the body of the targeted individual by delivery of one or more novel compositions of fenugreek seed extract contemplates the step of ingesting or otherwise administering (e.g., parenterally) a form of the composition extract and enabling the composition to reach the tissues of the individual such that the fenugreek seed extract facilitates and supports the transport and metabolism of glucose and carbohydrates. As will be discussed hereinbelow, greater concentrations of bio-active compounds in the administered composition yields greater stimulated insulin production, whereby indicating the effectiveness of the novel compositions and methods of producing same in stimulating insulin production in humans.

It will be apparent that a variety of other methods for performing weight management 6, performing fenugreek seed extraction 10 and enhancing skeletal muscle glucose transportation 8 within a targeted individual may be performed in accordance with the inventive principles set forth herein and which are consistent with the spirit and scope of the present invention. It is intended, therefore, that the examples provided herein be viewed as exemplary of the principles of the present invention, and not as restrictive to any particular method, technique, step or ordering of steps for implementing those principles.

One presently preferred embodiment of a method of the present invention for extracting a composition of bio-active compounds, including 4-hydroxyisoleucine and an array of other amino acids, from fenugreek seeds is best illustrated in FIG. 2. Preferably, the method for extracting a composition of bio-active compounds from fenugreek seeds 10 comprises the steps of: (1) preparing the fenugreek seeds 15; (2) performing a preliminary extraction process 20; and (3) performing a secondary extraction process 25. Of course, the extraction method may include other steps, as appreciated by those skilled in the art, in order to more optimally extract those useful bio-active compounds from fenugreek seeds.

Referring now to FIGS. 2 and 3, the step for preparing fenugreek seeds 15 may include the steps of: (1) providing the fenugreek seeds 40; (2) soaking the fenugreek seeds 42; and (3) crushing the fenugreek seeds 44. The soaking step typically involves soaking the seeds in water for a specified amount of time. Other solutions capable of providing the preparative properties of water may also be used. After the seeds have been soaked, the step of crushing the seeds 44 effectively separates various parts of the seed. For example, the crushing step 44 may separate the thick or hard outer coat of the seed, referred to as a testa 48, from the inner portion of the seed, known as the endosperm 46. As appreciated, the endosperm 46 is a nutritive tissue that surrounds the plant embryo.

Referring now to FIGS. 2 and 4, the step of performing a preliminary extraction process 20 from the endosperm 46 and the testa 48 resulting from the preparation steps 15 may include an extraction step 50 using a solvent (Solvent I). For example, Solvent I may include a compound such as hexane, cyclohexane, ether or any combinations thereof. The extraction step 50, as contemplated herein, effectively de-fats the seeds. Accordingly, after performing the preliminary extraction process 20, the product may be referred to as “de-fatted.” The extraction step 50 may also involve repeatedly heating the combination of prepared seeds and Solvent I. In one presently preferred embodiment of the present invention, the combination of seeds and Solvent I may be heated three (3) times to temperatures ranging from between about 20° C. and 90° Celsius. (C). More preferably, the combination of seeds and Solvent I may be heated three (3) times to temperatures ranging from between about 65° C. to 70° C. The combination of prepared seeds and Solvent I may be maintained at these elevated temperatures for any of a range of time periods sufficient to achieve the desired results. In one presently preferred embodiment of the present invention, the combination of prepared seeds and Solvent I are maintained at elevated temperatures from about 1 to 3 hours. Consequently, the extraction step 50 typically yields a seed extract 52 and a seed residue 53.

Referring specifically to FIG. 4, a distillation and concentration step 54 may be performed on the fenugreek seed residue 53. As appreciated, the distillation and concentration step 54 may make use of a variety of conventional means to distill and concentrate extracts from the fenugreek seed. For example, distilling a seed residue obtained from successive extractions with a first solvent using a fractionating column may be accomplished by heating the seed residue until boiling, capturing and cooling the heated vapors. The distillation and concentration step 54 may yield quantities 56 of recovered Solvent I, as well as, fenugreek seed oil, diosgenin, fenugreek isoflavone, fenugreek saponin, and a soluble fiber, such as galactomannan or the like.

An extraction step 60 using a solvent (Solvent II) may be performed on the concentrated seed extract 52. Solvent II preferably comprises a solution including ethanol or a solvent having similar chemical properties to ethanol. The concentration of ethanol used in the extraction step 60 may assume a variety of values. For example, the ethanol concentration may vary between the values of about 10% and 95%. In one presently preferred embodiment of the present invention, the extraction step 60 further involves the step of repeatedly heating the combination of seed extract 52 and Solvent II. Preferably, the combination may be heated three (3) times to temperatures ranging from between about 20° C. and 90° C. More preferably, the combination of seed extract 52 and Solvent II may be heated three (3) times to temperatures ranging from between about 65° C. and 70° C. In one presently preferred embodiment of the present invention, the combination of seed extract 52 and Solvent II may be maintained at these elevated temperatures for a broad range of time periods sufficient to achieve the desired results. For example, the combination of seed extract 52 and Solvent II may be maintained at elevated temperatures from about 1 to 3 hours. In this regard, the extraction step 60 typically yields a seed residue 62 and a concentrated seed extract 64.

Additional steps associated with the preliminary extraction process 20 may include a concentration step 66 performed on the concentrated seed extract 64. The concentration step 66 preferably comprises the use of a vacuum to separate quantities of solvent 68 and a concentrate 70. The separated concentrate 70 may then subject to a step of cooling and settling 72 to yield a sediment 74, including crude proteins, and a supernatant 76. A dilution step 78 may then be applied to the supernatant 76 to produce a diluted supernatant 80. As appreciated, the dilution step 78 may involve the addition of de-ionized water. The volume of water added may vary. For example, the amount of water added in one presently preferred embodiment of the dilution step 78 of the present invention may include about 2 to 10 times the volume of the supernatant 76. After dilution, the diluted supernatant 80 may then undergo a secondary extraction process 25, as described in FIGS. 2, 5 and 6.

It will be apparent that a variety of other methods or steps of the preliminary extraction process 20 may be performed in accordance with the inventive principles set forth herein and which are consistent with the spirit and scope of the present invention. It is intended, therefore, that the examples provided herein be viewed as exemplary of the principles of the present invention, and not as restrictive to any particular method, technique, step or ordering of steps for implementing those principles.

Referring to FIGS. 2 and 5, the diluted supernatant 80 produced as a result of the preliminary extraction process 20 preferably undergoes a secondary extraction process 25. In one presently preferred embodiment of the present invention, the secondary extraction step 25 may include the step of adjusting the pH 100 of the diluted supernatant 80. The step of adjusting the pH of the diluted supernatant 100 may include the use of a variety of solutions. For purposes of example, and not by way of limitation, hydrochloric acid may be used. The concentration of ingredients of the pH adjusting solution may have a variety of values. As appreciated, the pH of the diluted supernatant 80 may be adjusted to any of a range of values sufficient to accommodate the desired results. Accordingly, the solution of hydrochloric acid may facilitate an adjustment in the pH of the diluted supernatant 80 to a pH in a range of between about 1 and 6.5.

The pH adjusted diluted supernatant 80 may then undergo a cation ion exchange resin filtering step 104. In one presently preferred embodiment, the filtering step 104 involves running the pH adjusted supernatant 80 through a resin. The cation ion exchange resin is typically macroporous and may be weakly polar or non-polar. The treated resin may then undergo a washing step 108 which may include washing the resin with water.

The following examples will illustrate the practice of the present invention in further detail. It will be readily understood by those skilled in the art that the following methods, formulations, and compositions of a unique, high-potency, bio-active fenugreek seed extract of the present invention, as generally described and illustrated in the Examples herein, are to be viewed as exemplary of the principles of the present invention, and not as restrictive to a particular structure or process for implementing those principles. Thus, the following more detailed description of the presently preferred embodiments of the methods, formulations, and compositions of the present invention, as represented in Examples I-VI, is not intended to limit the scope of the invention, as claimed, but is merely representative of presently preferred embodiments of the invention.

EXAMPLE I Syrian Golden Hamster—15 mg/mL

A unique, high-potency bio-active extract is prepared from fenugreek seeds according to a presently preferred embodiment of a fenugreek seed preparation process 10 of the present invention. More particularly, a concentration of 15 mg 4-hydroxyisoleucine per mL is prepared from the yield of process 10. This concentration is administered to an in vitro cell line: HIT-T15, a Syrian golden hamster pancreatic islet of Langerhans beta cell and evaluated for changes in the concentration of insulin activity over time.

Referring now to FIG. 7, a procedure for preparing a cell culture and evaluating the bio-activities of fenugreek extract in cultured pancreatic beta cells from a Syrian golden hamster 140 is illustrated. In one presently preferred embodiment of the present invention, a cell culture 142 from HIT-T15 may be obtained and the cells may be subcultured 144 by removing a growth medium and adding about 4 mL of a solution containing about 0.05% trypsin and 0.53 mM EDTA and gently washing for approximately 5 seconds. The solution may be removed and 4 mL of fresh solution may be added. The cells may be incubated at about 37° C. for approximately 7 minutes. Following detachment, the harvested cells are counted 146 in a manner readily known to those skilled in the art. Once such manner may utilize a Tryptan Blue exclusion method with a hemacytometer. Next the harvested cells are preferably diluted in culture medium 148. A culture medium may comprise Ham's F-12, which is sometimes referred to as Knight's modification or F12K. The cell dilution may be re-plated at 1,500 cells per well 150 in a 24-well plate. Unused cells may then be placed into a 75 cm² flask. The well plates may continue in culture 152 for about 2 days. Following the completion of the continue in culture 152, the cultured pancreatic beta cells from a Syrian golden hamster may be subjected to tolbutamide 154 and DMSO 156 as positive and negative controls, respectively, and may also be subjected to a concentration of fenugreek seed extract 158.

Referring now to FIG. 8, a graph representing the results of test conducted using pancreatic beta cells from a Syrian golden hamster cultured according to the preparatory procedure 140 and evaluated following exposure to a concentration of a composition of bio-active compounds derived from fenugreek seed extract at 15 mg 4-hydroxyisoleucine per mL is shown. As can be seen from the plot, after addition of the components at time equals zero, insulin levels grew steadily until peaking at time equals 40 minutes and then falling to the insulin level measured before the addition of the components. As appreciated by those skilled in the art, and as depicted in FIG. 8, measurements taken of the insulin activity level in a pancreatic beta cell of a Syrian golden hamster over the course of the experiment indicate that the composition of bio-active compounds derived from fenugreek seed affects the level of insulin in an animal subject.

EXAMPLE II Fenugreek Seed Extract in Syrian Golden Hamsters—60 mg/mL

As previously described in Example I and as illustrated in FIG. 7, a preparatory procedure 140 was used to culture, harvest, and evaluate pancreatic beta cells from a Syrian golden hamster. Referring now to FIG. 9, a schematic graph illustrates the results from this test. Pancreatic beta cells from a Syrian golden hamster were cultured according to the preparatory procedure 140 and evaluated following exposure to a concentration of the bio-active components of a fenugreek seed extract (e.g., Promilin™) at 60 mg 4-hydroxyisoleucine per mL. As shown, greater concentration of bio-active compounds yielded greater stimulated insulin production. As appreciated by those skilled in the art, and as depicted in the illustration, measurements taken of the insulin activity level in a pancreatic beta cell of a Syrian golden hamster over the course of the experiment indicate that the bio-active components do affect the level of insulin in an animal subject.

It is readily appreciated that tests conducted using pancreatic beta cells from a Syrian golden hamster cultured according to the presently preferred embodiments of the preparatory procedure 140 of the present invention and evaluated following exposure to a concentration of a composition of bio-active compounds derived from fenugreek seed extract (e.g., Promilin™) prepared in accordance with the fenugreek seed preparation process 10 may be configured to apply to any number of embodiments for practicing the present invention which are consistent with the spirit and scope of the present invention. It is intended, therefore, that the examples provided herein be viewed as exemplary of the principles of the present invention, and not as restrictive to a particular structure or method for implementing those principles.

EXAMPLE III Non-Debitterized Fenugreek Seed Extract in Humans—1 mg 4-hydroxyisoleucine/kg

Generally referring now to FIGS. 10-19, tests were conducted with three healthy male human subjects who had no history of diabetes or carbohydrate metabolism dysfunction. The test included two procedures. For the first procedure the subjects fasted overnight. Blood samples were taken from the subjects for glucose and insulin level measurements at time equal to negative 30 minutes, 0 minutes, 15, 30, 60 minutes, 120 minutes, and 180 minutes. At time equal zero, a solution of 75 gram (g) of glucose in 300 mL water was administered to the subjects. The insulin content of each of the blood samples was measured using Radioimmunassay (RIA) at the School of Pharmacy at University of Montana. The results of the blood sample testing is graphically summarized in FIGS. 10-20 as the “placebo portion” data points. As appreciated by those skilled in the art, this type of test is similar to an oral glucose tolerance test (OGTT), which is used in the diagnosis of diabetes and gestational diabetes. In the presently preferred embodiment of the present invention, the first procedure serves as a control mechanism to quantify the baseline level of blood glucose and concentration of insulin activity.

The second procedure was performed under the same conditions as the first procedure. The only difference being that a composition of bio-active compounds derived from fenugreek seed (e.g., Promilin™) were administered to three human subjects. Again, referring generally to FIGS. 10-19, the active solution contained 75 g of glucose in 300 mL of water as well as a dose of fenugreek extract (e.g., Promilin™) between 1-9 mg 4-hydroxyisoleucine per kg of subject body weight. The results of the second procedure are summarized in FIGS. 10-19 as the “active portion” data points.

In one presently preferred embodiment of the present invention, a unique, bio-active non-debitterized fenugreek seed extract composition (e.g., Promilin™) containing an array of twenty amino acids including 1 mg 4-hydroxyisoleucine per kg body weight was administered to human individuals. The resulting composition was administered to a first human subject.

Referring specifically to FIG. 10, a schematic plot illustrates the placebo portion and active portion results in the first human subject. The active portion contained 75 g of glucose in 300 mL of water as well as one presently preferred embodiment of the present invention comprising a unique, high-potency fenugreek seed non-debitterized extract of bio-active compounds (e.g., Promilin™) at a concentration of 1 mg 4-hydroxyisoleucine per kg body weight.

As depicted in the graphical illustration, measurements taken of the insulin activity and glucose level in the first human subject over the course of the experiment indicate that the composition of bio-active compounds derived from fenugreek seed (e.g., Promilin™) affects the level of insulin and glucose in the human subject. It is readily seen that after time equals zero the insulin activity levels of the first human subject were higher for the active solution containing the bio-active compounds and that the glucose levels are lower.

Referring now to FIG. 11, a schematic plot illustrates the placebo portion and active portion results in a second human subject. The active portion contained 75 g of glucose in 300 mL of water as well as one presently preferred embodiment of the present invention comprising a unique, high-potency fenugreek seed non-debitterized extract of a composition of bio-active compounds derived from fenugreek seed (e.g., Promilin™) at a concentration of 1 mg 4-hydroxyisoleucine per kg body weight.

As depicted in the graphical illustration, measurements taken of the insulin activity and glucose level in the second human subject over the course of the experiment indicate that the composition of bio-active compounds (e.g., Promilin™) affects the level of insulin and glucose in the human subject. It is readily seen that after time equals zero the insulin activity levels of the second human subject rose remarkably beyond pre-administration levels for measurements taken following administration of the active solution containing the bio-active components and that the glucose levels are lower.

It is readily appreciated that the tests conducted on the first and second human subjects to evaluate the results of exposure to a composition of bio-active compounds derived from fenugreek seed extract prepared in accordance with the fenugreek seed preparation process (e.g., Promilin™) may be configured or modified to apply to any number of embodiments for practicing the present invention which are consistent with the spirit and scope of the present invention. It is intended, therefore, that the examples provided herein be viewed as exemplary of the principles of the present invention, and not as restrictive to a particular structure or method for implementing those principles.
